We have improved our categorization of puzzles by type of design features, so now it's easier to find a good listing of double-sided puzzles, puzzles with irregular edges, and puzzles with different types of pieces.
We are also working on adding a Puzzles By Piece Count categorization again, that will be linked from the Home page once it's ready.
Fixed! Thank you!
Cool! fyi, the link to "mini hex " puzzles goes to the irregular edge puzzles instead.
